Influent Substrate Concentration given Theoretical Oxygen Requirement Solution

Follow our step by step solution on how to calculate Influent Substrate Concentration given Theoretical Oxygen Requirement?

FIRST Step Consider the formula

S o = (O 2 + (1.42 \cdot P x)) \cdot (\frac{f}{8.34 \cdot Q a}) + S

Next Step Substitute values of Variables

∴

S o = (2.5mg/d + (1.42 \cdot 20mg/d)) \cdot (\frac{0.68}{8.34 \cdot 1.2m³/d}) + 15mg/L

Next Step Convert Units

∴

S o = (2.9E-11kg/s + (1.42 \cdot 2.3E-10kg/s)) \cdot (\frac{0.68}{8.34 \cdot 1.4E-5m³/s}) + 0.015kg/m³

Next Step Prepare to Evaluate

∴

S o = (2.9E-11 + (1.42 \cdot 2.3E-10)) \cdot (\frac{0.68}{8.34 \cdot 1.4E-5}) + 0.015

Next Step Evaluate

∴

S o = 0.0150020995203837kg/m³

Next Step Convert to Output's Unit

∴

S o = 15.0020995203837mg/L

LAST Step Rounding Answer

∴

S o = 15.0021mg/L
